Hey hey hey, it's episode 104 of the podcast. Recorded Wednesday May 6th, Matt and Jessamyn and I yammer for nigh on two hours about a bunch of great stuff from the last month and also complain about cell phone reception.

I don't know if this is the place to talk about the oldest story thing, but a cheap way to do the permalinks is store the seed value for your random number generator in the url, and just rebuild from that.posted by jonbro at 5:35 PM on May 6, 2015 [1 favorite]

I am googling that "104 is the smallest number of unit line segments that can exist in a plane with four of them touching at every vertex." thing and coming up with nothing. Would be obliged if someone could help me.posted by jessamyn(retired) at 5:38 PM on May 6, 2015

That sounds underspecified in the "four of them touching at every vertex". Can this be stated more precisely?posted by kenko at 5:40 PM on May 6, 2015

My guess was that it's saying: for a given set of equal-length line segments, arrange them in a connected graph such that both endpoints of each line segment share a vertex/node with exactly three other line segment endpoints. And that 104 is the minimum number of line segments with which you can create such a graph.

I'm imagining some strange donut-like arrangement of line segments, but that might just mean I'm hungry.posted by cortex(staff) at 5:48 PM on May 6, 2015

I think it's saying you can take 104 toothpicks and arrange them on a table so that each tip of each toothpick touches 3 other toothpicks' tips. I think the middles of the toothpicks can't touch, otherwise it would be really fiddly to actually do.posted by aubilenon at 5:52 PM on May 6, 2015

Neat, escabeche. And that Harborth graph could be a sort of fucked up donut, after all.

Also, wiki wandering lead me from there to the concept of a Matroid, which I don't understand but am going to assume was followed by Matroid II, Super Matroid, and eventually a Gamecube release called Matroid Prime.posted by cortex(staff) at 7:21 PM on May 6, 2015 [2 favorites]

Thanks for mentioning the Pluto Facts. I'm REALLY excited about the upcoming New Horizons flyby, so I've been thinking a lot about good old Pluto. I came up with something like 20 facts on a Saturday & another 10 the next Sunday morning, so I had a good stockpile when I started out, & am trying to keep ahead with enough material to last through the flyby in June or July.

I need to check on whether Pink Floyd mentions Pluto in Astronomy Dominie. We could get some synergy going there! (Even if it doesn't, that's a Pluto fact)posted by Devils Rancher at 9:38 PM on May 6, 2015

Why the Brunching post: basically, a few months ago I was feeling very say that so many things I like had ended, and decided to celebrate one of those things, partly as a way of cheering myself up, and also nurturing a secret hope it might inspire Lore to create something new, because people out here in Internet Land still remember him. At first I aimed it for December, but then figured maybe I was aiming for the contest, and I could wait a bit longer and make it better. Then I basically forgot about it for a while, and it sat in my text work folder along with the hundreds of other files in there.

Then I did the trial for a shareware meta-word-processing program, oriented towards large document planning, research, structuring and production, and figured a good test of what it could do would be finishing up one of those dusty megaposts. (By the way, it worked pretty well for that purpose I think; I bought a license, and look forward to it helping me with posts in the future.)

So to reiterate -- there was no special reason other than remembering that Brunching Shuttlecocks existed, that I and some friends loved it once, and figuring that I should act on that love, to actualize it, because a feeling that exists only in the mind is as nothing, and both to commemorate it and hopefully encourage more stuff like it.posted by JHarris at 3:21 AM on May 7, 2015 [4 favorites]

Also, on it being good that megaposts are rare things: they take so long to put together that I think it's safe to say that I won't be increasing my own rate at making them anytime soon, heh.

"104 is the smallest number of unit line segments that can exist in a plane with four of them touching at every vertex."

Yep, I don't think that Wikipedia statement is completely accurate, because you need to add the qualifier that the line segments are not allowed to cross for it to be true. A graph which can be drawn with all edges as unit line segments is a unit distance graph. A unit distance graph which can be drawn with no crossings is a matchstick graph.

So the Harborth Graph, as posted before, is the smallest known (not proven, as far as I can tell, and as that Wikipedia statement might imply) matchstick graph where every vertex connects four edges. But there are much smaller unit distance graphs where that is true; see for example the rightmost graph in Fig. 17 (p. 22) in this PDF, which is the generalized quadrangle (2,1), and has just 18 edges.posted by DevilsAdvocate at 6:51 AM on May 7, 2015 [1 favorite]

zarq, if you've got a Mac the two I like the most are Scrivener and Ulysses. Ulysses in particular is one of the best-designed programs I've ever used; it's a real functional design inspiration for me.

(I don't use either, though, because Notational Velocity and its slightly more powerful cousin nvALT are the greatest things since sliced bread. They're not meta-word-processors, however.)posted by rorgy at 7:38 AM on May 7, 2015 [1 favorite]

zarq: I didn't want to mention it right off lest it look like I was promoting it or something. rorgy already mentioned it though, it is Scrivener. I like that it can rapidly turn a series of individual entries in an organizer-like view into a complete document.

And I'm sorry if that comment above seemed stream-of-consciousness-y, it seems when I'm about to go to sleep that my ability to structure coherent thoughts in text doesn't quite measure up to what I think it is.posted by JHarris at 10:44 AM on May 7, 2015

(And to rorgy: Ulysses, eh? Will keep an eye out for, although Scrivener has the advantage of being out for Windows.)posted by JHarris at 10:46 AM on May 7, 2015

Ulysses comes very close to my dream text editor. It's a Markdown-powered processor with robust support for tagging, organizing, and publishing, and can do fancy things like automatically merge multiple documents into a single visible file without actually removing the document structure. If you're writing a 20-chapter book and want to publish the thing as a single PDF, you just select all 20 chapters, and Ulysses loads them as a single entity.

But mostly it's just that it has the best-crafted text design I've found in any program, enough so that it makes writing in it a joy to use. It also uses a Notational Velocity-esque approach for listing all your files, which, post-Notational, is pretty much a must-have for me and text editors, and is one of a couple dings against Scrivener. (The other big one is just that I find Scrivener's organizational philosophy runs counter to my own, in some egregious ways.) It's a powerhouse that feels utterly lightweight, which is fantastic.

The downside to Ulysses is its reliance on proprietary text formats, an issue which Scrivener shares. Partly I just don't feel comfortable with any program that makes getting my shit out of it difficult; partly it means I can't use it on iOS nearly as easily as I can use a program that lets me Dropbox-sync all my stuff. Ulysses for iPad is out/awesome, but the only iPhone solution is Dedalus, by the same company, a quirky and annoying program that I can't use effectively to save my life.

The coup de grace, however, is that the actual best text-editor I've ever used is Editorial, which is so well-designed that it makes typing on an iPhone touch screen nearly more convenient than typing on a full-size keyboard. When you combine it with a good Bluetooth keyboard, it basically becomes my dream text editor — I will gladly overlook its general ugliness for its absolutely brilliant utility. (That it doubles as a to-do organizer is just icing on the cake.) And Editorial supports plaintext and Markdown, so now the ultimate benchmark for me and any app is, "Can I use it with Editorial?" If the answer is no, then the app must go.

(Not even gonna pretend like I'm offering useful information to y'all at this point. I just love prattlin' on about writing applications. It's amazing to me how little developers have paid attention to the writing workflow, just because a keyboard and plaintext editor technically "does the trick". I'm not counting publishing engines like Wordpress or layout programs like Word here, since neither one is focused on the actual thing that matters to me, and that's understanding writing as an art as structured as music or painting, but with tools about a hundredth as good at conveying that complexity on account of fuck everybody, I don't even know. Good writing programs make me weep happy tears, that's all.)posted by rorgy at 12:05 PM on May 7, 2015 [5 favorites]

It's okay, prattle away! Although I understand that under the hood Scrivener actually uses RTF files in directories, which while not plain text or anything can still be opened in many word processors. I can't compare it to Ulysses, but I've been pretty satisfied with it.posted by JHarris at 12:51 PM on May 7, 2015 [1 favorite]

Is there a link to the transcript?

Pronoiac was out at a thing last night, so he may not have set it up yet.

Man, I have used (and enjoyed) Scrivener but couldn't get past Ulysses' twee "voice" on its FAQ and general web pages. But I'm not in need of an editor atm so I'll just keep listening. I use Taco HTML edit the way some people use emacs.posted by jessamyn(retired) at 1:29 PM on May 7, 2015

I don't think that Wikipedia statement is completely accurate, because you need to add the qualifier that the line segments are not allowed to cross for it to be true.

Wait. Serious question. Once line segments cross on a 2D plane, don't they basically become the equivalent of 4 line segments that converge on a point? Like, the end points of the line are A-B and C-D, and they cross at X... don't they basically become A-X, B-X, C-X, D-X?

Is the point of this exercise that all the unit line segments never meet at a 180-degree angle because at that point they could be considered the same line?posted by hippybear at 3:34 AM on May 8, 2015

No, a unit line segment is still a unit line segment even if it is crossed by other things. I.e., if you have a unit line segment AB, and plop down a point X along that (possibly because another line segment has crossed it at X), you've created line segments (with length less than one unit) AX and XB, but that doesn't stop AB from still being a unit line segment.

Is the point of this exercise that all the unit line segments never meet at a 180-degree angle because at that point they could be considered the same line?

No, not necessarily. If you have unit line segment AB, and unit line segment BC, and they meet at a 180 degree angle, then you also have line segment AC with length two, but AB and BC are still unit line segments. In fact, in the Harborth graph a number of the line segments involved meet at 180 degree angles.posted by DevilsAdvocate at 5:28 AM on May 8, 2015

This is the case because programmers have a different relation to the plaintext editor than most people. I've spent 3 years learning vim and will probably never plumb all of its voluminous depths or use its outrageous power, and emacs, no matter its faults, I must say is deeper yet than vim.posted by curuinor at 10:43 AM on May 8, 2015 [1 favorite]

Here in Germany they are absolutely called Deutsche Dogge as an everyday thing, and when it's pronounced correctly by a German-speaking person in Germany it makes total sense. It's also more fun to say than 'Great Dane' (at least in my terrible German accent).

There's no link to the doge meme here because, firstly, it's pronounced differently and secondly, that meme doesn't seem to have any traction here (at least amongst the people I know, which is a very limited sample).

Also they come in the same colours as my cats so I have a not-so-secret fantasy of getting matching pets.posted by shelleycat at 2:37 AM on May 9, 2015 [2 favorites]

Or at least, I've never seen any link to the doge meme even after having a couple of different conversations about these dogs, doesn't mean it doesn't exist elsewhere of course. I don't speak German so I'm not exactly integrating.posted by shelleycat at 2:53 AM on May 9, 2015

I've moved from vi to Sublime for any of my more involved programming efforts in the last years and I'm really loving it. vi is still my go to from a shell, but having, yeah, actual modern tools to help interact with code turns out to be a pretty nice deal, even if I panic when I accidentally hit Sort Lines on a thousand lines of JS.posted by cortex(staff) at 8:36 AM on May 9, 2015

"Someone has it registered somewhere, I'm pretty sure, oh well. /clicks 'do it later'" - lots of people in lots of offices with Sublime.

If you use it you absolutely should cough up for it, but there's little practical barrier to trying it out, DRM, indefinitely.

Atom and the new multiplatform VS look interesting also.posted by Artw at 1:54 PM on May 9, 2015 [1 favorite]

Yeah, it'll just nag you periodically if you haven't paid for it, so giving it a go for a while for free is a totally viable thing. I balked at the price at first two, but it turned out from giving it a long test-run that it's really that good.posted by cortex(staff) at 1:58 PM on May 9, 2015

Atom and the new multiplatform VS look interesting also.

Atom is just fine for most things, but its current inability to handle files larger than two MB is a real killer.posted by Going To Maine at 2:12 PM on May 9, 2015

I dunno though, I feel bad about using shareware without paying for it, and nag screens threaten to turn me into some kind of hulk. Not an incredible one, though, in fact one that is generally quite believable. Actually, not a hulk so much as me but slightly red-faced and making noises like grrrr.

Notepad++'s pretty swell anyway.posted by JHarris at 4:56 PM on May 9, 2015

If you're like me, you like to edit C source with a tab size of 4, plain text with a tab of 8 and text wrapping enabled, and HTML with all the tabs inserted as spaces. Oh, and we'd like C source to be red on blue, but HTML looks much nicer as cyan on yellow, if you wouldn't mind

We're using a tab of two round our way. Mind you were using some languages where whitespace counts*, so it would be awful otherwise.

Jessamyn, you could get some magnetic tape or big Post-Its and use it to make cards with HTML primitives (you know, opening and closing style tags: <EM> one one and </EM> on another), and then stick those to your whiteboard to surround some Lorem Ipsum text.

I wanted to ask, "has anybody ever made a magnetic poetry supplement that's just a bunch of self-contained and matching opening and closing html tags, so you could mark up your magnetic poetry explicitly?", but I think just asking it is kinda silly because (a) maybe they did but no one knows, and (b) maybe they didn't but how would anyone know that their personal lack of awareness of it is actually definitive of it not having happened, and in any case (c) while I'm sure you can still buy the stuff in gift shops and such, it seems like as a consumer phenomenon it has fallen way, way off the map from twenty years ago.

But anyway maybe you could buy and use that, Jess.posted by cortex(staff) at 7:40 AM on May 18, 2015
